How it settles
We read the arrival time the destination airport publishes, against its published schedule. A flight that arrives more than the delay threshold late settles "Delayed"; one that arrives exactly on the threshold settles "On time". The threshold and the scheduled arrival it is measured against are fixed when the market opens — so the outcome is decided by the flight, not by anyone here.
A trade accepted after the flight's arrival was first published is voided and refunded in full, including any fee (a bonus trade to your bonus balance). Publication is dated by the flight-data message's own time, or by when an airport's board served the arrival to us; if the recorded arrival time is earlier, it is the cutoff instead.
This market's delay threshold is 15 minutes.
